BRAIDING-MACHINE.

LSPECFICATION forming part of Letters Patent No. 727,926, dated vMay 12,1903.

Application filed PebruaryZl, 1903. Serial No. 144.769. (No model.)

To all whom, it may concern:

Beitknown thatI,JOHN J. FEELEY, a citizen of the United States, residingat Manton, in the county of Providence and State of Rhode Island, haveinvented a new and useful Improvement in Braiding-Machjnes, of which thefollowing is a specication.

This invention has reference to an im provement in braiding-machines,and more particularly to an improvement in the thread tension anddelivery mechanism on the movable racers of braiding-machines.

In movable racers for braiding-machines as heretofore constructed thetension-weight sliding on its support abuts directly against the lowerend of the latch. The latch sliding on the same support above thetension-weight has an arm extending over the bobbin to engage with teethon the head of the bobbin, andthe upper end of the support is contractedto allow the removal of the latch and t-ensionweight. The draft of thethread on the tension-Weight lifts the weight and latch. The draft ofthe thread may lift the latch beyond its normal operative position andinto the contracted portion of the support. Thelatch, being lifted fromits lower end and overhalanced by the weight of its ou tWardly-extendingarm, fails to engage with a stop on the upper end of the support andfalls outward from the contracted portion of the support, preventing theproper operation ot' the teusion and delivery mechanism.

The object of my invention is to so lift the latch that when carriedupward and out of its normal operative position it will engage with thestop on the support and when released will drop back into its normalposition.

My invention consists'in the peculiar and novel construction of thetension-weight havingan upwardly-extendingarmengagingwith the latch-armt-o lift the latch at a point that will prevent overbalancing of thelatch, as will be more fully set forth hereinafter.

Figure 1 is a side View of a movable racer for braiding-machines,showing my improved tension-weight with its upwardly-extending arm inengagement with the latch-arm at a point to prevent overbalancing of thelatch. Fig. 2 is an enlarged detail View of the thread tension anddelivery mechanism looking from the bobbin side of the mechanism, withits racer, and showing myimproved tensionweightin its operative positionwith the latcharm; Fig. 3 is a sectional view taken lengthwise throughFig. 2. FgglE is a transverse sectional View taken on line X X of Fig.2,

showing the latch and its support; and Fig.,

5 is a transverse sectional view taken on line Y Y of- Fig. 2, showingthe means of holding the tension-weight on its support.

In the drawings, a represents a bobbin having the teeth a. a (usuallysix in number) on its upper or head end. The bobbin a is placed on avertical spindle-projecting upward from the frame b. Extending upwardfrom the frame b is the support hf for the thread tension and deliverymechanism. The support b forms a guide for the tension-weight@ andthelatch d and has the'contracted portion b2 on its upper end, the stop b3,and the guide-eyes h4 and b5 for the thread. rlhe tension-weight c,sliding on the support b', has the lips c c shaped to loosely fit thesupport and form the elongated openings c2 c2 slightly wider than thecontracted portion b2 of the support. On the outer lower edge of thetension-weight c is the slot c3, forminga guide for the thread, and onthe inner side is the upwardly-extending arm c4 to engage with thelatch-arm. The latch d, sliding on the support b' above the4tension-weight, has the lips d d', loosely itting the support andforming the elongated opening d2, slightly wider than the contractedportion b2 ot the support, and the arm d3, extending outward and overthe upwardlyextending arm c4 on the tension-weight and engaging with theteeth a a on the bobbin.

In the operation of the thread tension and delivery mechanism with myimproved tension-Weight the thread coming from the bobbin passes throughthe guide-eye b4 in the support, then downward and through the slot c3in the tension-weight, then upwardand through the guide-eye b5 in thesupport to the point where the several threads in themachine are braidedtogether. The drat't of the-thread as it comes from the bobbin raisesthe tension-weight c. This'in turn, through the upwardly-extending armc4 engaging with the arm d3 on the latch d, raises the latch, with thearm d3, from the teeth a' on the bobbin, allowing the bobbin to revolveone tooth.

support broken away ffrom the frame of the The latch now falls bygravity and catches the next tooth on the bobbin. This operation isrepeated indefinitely, deliveringa predetermined amount of thread foreach npward movement of the latch. If the latch CZ should be carriedupward and out of its normal operative position, the arm c4 on myimproved tension-weight engaging With the arm d8 on the latch wouldprevent the latch from overbalancing and falling out and cause it toengage with the stop b3 on the support b', when it Would drop back intoits normal position on the support b' by gravity.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. Ina movable racert'orbraiding-machines, a framehaving a spindle and bobbin, a support on the frame, a slidingtension-Weight on the support, a sliding latch on the support with anoutwardly-extending arm to engage with teeth on the bobbin, and means onthe tension-eight to engage with the latch at a point to preventoverbalancing of the latch by the Weight of the latcharm,\vhen the latchis raised out of its normal operative position by the draft of thethread on the tensionweight, as described.

2. In a movable racer for braiding-machines, the combination with thebobbin a having the teeth a d', the frame b having a spindle for thebobbin, and the support b with the contracted portion b2, the stop b3,and the guide-eyes b4 and b5, the tension-Weight c With the lips c c'forming the elongated openings c2 c2, the slot c3, and theupwardly-extending arm c4, the latch d having the lips d d' forming theelongated opening cl2, and the arm d3 extending outward and over theupwardlyextending arm c4 on the tension-weight and engaging with theteeth on the bobbin, all for the purpose as described.

In testimony whereof I have signed my name to this specication in thepresence of two subscribing witnesses.

JOI-IN J. FEELEY.
